[libvirt] [PATCHv5 0/4] Add support for memory backing with file source

Hi, we would like to introduce 3 new elements source,access and allocation in memoryBacking element. For now it was made for numa topology. <memoryBacking> <source type="file|anonymous"/> <access mode="shared|private"/> <allocation mode="immediate|ondemand"/> </memoryBacking> If allocation is immediate then -mem-prealloc should be added to the qemu commanline. If source is file then -object memory-backend-file,id=mem,size=1024M,mem-path=*lib dir path* -numa node,memdev=mem Will be added to the qemu commandline If access is shared then the "share=on" parameter will be added to the memory-backend-file e.g. -object memory-backend-file,id=mem,size=1024M,mem-path=/var/lib/libvirt/qemu,share=on The access mode can be overriden by specifying token memAccess in numa cell. The mem-path can be defined by new config parameter memory_backing_dir. PS: the sometime failing test qemuhotplug was failing also before this patch :) Jaroslav Safka (4): qemu,conf: Rename virNumaMemAccess to virDomainMemoryAccess qemu_conf: Add param memory_backing_dir conf: Add new xml elements for file memorybacking support qemu: Add args generation for file memory backing docs/formatdomain.html.in | 9 ++ docs/schemas/domaincommon.rng | 30 +++++ src/conf/domain_conf.c | 133 ++++++++++++++++----- src/conf/domain_conf.h | 22 ++++ src/conf/numa_conf.c | 15 +-- src/conf/numa_conf.h | 14 +-- src/qemu/libvirtd_qemu.aug | 3 + src/qemu/qemu.conf | 4 + src/qemu/qemu_command.c | 55 ++++++--- src/qemu/qemu_conf.c | 9 ++ src/qemu/qemu_conf.h | 2 + src/qemu/qemu_process.c | 2 +- src/qemu/test_libvirtd_qemu.aug.in | 1 + .../qemuxml2argv-fd-memory-no-numa-topology.args | 21 ++++ .../qemuxml2argv-fd-memory-no-numa-topology.xml | 27 +++++ .../qemuxml2argv-fd-memory-numa-topology.args | 24 ++++ .../qemuxml2argv-fd-memory-numa-topology.xml | 30 +++++ .../qemuxml2argv-fd-memory-numa-topology2.args | 27 +++++ .../qemuxml2argv-fd-memory-numa-topology2.xml | 31 +++++ .../qemuxml2argv-fd-memory-numa-topology3.args | 30 +++++ .../qemuxml2argv-fd-memory-numa-topology3.xml | 32 +++++ .../qemuxml2argv-memorybacking-set.xml | 24 ++++ .../qemuxml2argv-memorybacking-unset.xml | 24 ++++ tests/qemuxml2argvtest.c | 13 ++ .../qemuxml2xmlout-memorybacking-set.xml | 32 +++++ .../qemuxml2xmlout-memorybacking-unset.xml | 32 +++++ tests/qemuxml2xmltest.c | 3 + 27 files changed, 584 insertions(+), 65 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-no-numa-topology.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-no-numa-topology.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-numa-topology.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-numa-topology.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-numa-topology2.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-numa-topology2.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-numa-topology3.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-fd-memory-numa-topology3.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-memorybacking-set.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-memorybacking-unset.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-memorybacking-set.xml create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-memorybacking-unset.xml -- 2.7.4 -------------------------------------------------------------- Intel Research and Development Ireland Limited Registered in Ireland Registered Office: Collinstown Industrial Park, Leixlip, County Kildare Registered Number: 308263 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
